Fulham target their third successive League victory at Eastlands on Sunday.
Gera said: “They need more time to win the title. They have signed a lot of players, but for me it’s not this season they can win the League – maybe next season.
“But Manchester City are now a team just like Liverpool or Chelsea. It’s no longer a top four, it’s a top five.
“Look at Chelsea six years ago. They were a team who never won anything, but now they are always a big team. City can do the same.”
